Logic problem

June 14, 2009 · 8 Comments

Everybody have seen this before

All dogs have four legs
My cat has four legs
Therefore, my cat is a dog

I think we can all spot the problem here — my cat could be a dog, but since not only dogs have four legs, it does not have to be.  In fact, my cat is not a dog because of traits unrelated to the four legs.

Now, let’s try this

All good tea has X
This tea has X
Therefore, this tea is good.

Or

All old teapots has Y
This teapot has Y
Therefore, this teapot is old

Now, these statements can all be true — they are potentially true.  However, as we’ve seen in the first problem, they do not have to be true.  Quite the contrary, in fact.

A real life example that is widely used is this

All old tree puerh leaves have thick veins
This tea has thick veins
Therefore, this is an old tree puerh leaf

At one point I subscribed to this theory, or at least strongly entertained the possibility of it, but upon further reflection and observation, I have found this to be untrue.  I have seen teas that are obviously from large plantations (big factory stuff) that exhibit thick veins, therefore disproving this theory that thick veins prove a tree’s age.

It is pretty easy to fall into the trap of following along one of these flawed deductive reasoning, usually from a reputable seller or vendor or “expert” and then just taking the statement at face value and not thinking through the logical implications of the deductive process.  While it certainly may have been true that only old tree leaves have thick veins, there is no guarantee that this was the case without extensive evidence that all other kinds of tea tree leaves have no thick veins.

Another one

All old teapots are tea-stained
This teapot is tea-stained
Therefore this teapot is old.

Obviously it doesn’t have to be true again.

Now, with other supporting evidence, these statements could be true.  If we assume that zhuni is now extinct and has been for decades, for example (a point that is hotly debated everywhere), then we can probably say

All zhuni pots are made from clay that is extinct
This teapot is a zhuni pot
Therefore this teapot is made from clay that is extinct

Ok, that works, but if you change it to

All zhuni clay is decades old
This teapot is made with zhuni
Therefore this teapot is decades old

Well, somebody may point out that a potter may have harvested a lot of zhuni clay before it went into extinction, and is in fact still producing new pots using this old clay.  So, even though your clay is decades old, the pot is brand new.  In theory, this is possible.  In practice, how anybody can store (securely, I might add) tonnes of clay that seems inexhaustible is questionable.  Either way, the above statements do not convey the entire argument that will have to go into debating whether a pot is new or old.  Using one small trait as its definining characteristic is not exactly reliable if you don’t know all the other relevant facts.

This kind of reasoning works better in the other direction, actually.  Let say somebody devised a new way of pressing puerh cakes that embosses a mark on the cake itself

All embossed cakes are new
This cake is embossed
Therefore this cake is new

That would work since we know that the embossing process is new.  The first line should actually read

All embossed cakes can only be new

Then there’s no doubt as to what’s going on.

The problem with processes doesn’t work the other way though.

All old cakes were stone pressed
This cake is stone pressed
Therefore this cake is old.

Just because people used to do things a certain way doesn’t mean that somebody living now cannot recreate the same process, in this case pressing tea with stone moulds.  In fact, we know this is happening everywhere as tea makers revived the stone-pressed cake since the 1990s.

I guess the point of this post is — beware of these logic deductions based on one or two traits of whatever good that is being sold.  We all know that the job of the vendor is to sell you things.  It’s very easy to fall into the trap (as I did with the thick veins thing) of just assuming this to be true and then not realizing that it, in fact, is not.

Tea in Woodstock, VT

June 12, 2009 · Leave a Comment

Driving through Vermont today, stopping in a nice little town called Woodstock, and finding a shop called Tea and Coffee House there.  It’s nothing that’s going to impress a real tea addict, but it’s really nice to find a shop that tries to provide nice loose leaf tea in a pretty out of the way town.  Granted, it’s in the more tree-hugging part of the country with heavy ski tourists in the winter, but still, being able to buy a cup of shuixian (and not too horrid shuixian) from a shop instead of having to bring everything yourself (which I did anyway) was a nice change.  If only all towns in the US can say the same.  I do think though that over time, the incidence of shops that can provide something more than just basic “English Teatime” Bigelow teabags is going up, and that, I must say, is a really good thing.

Dahongpao, or Big Crimson Robe

June 7, 2009 · 8 Comments

My school’s colour is crimson, which is a kind of red.  Dahongpao, as you probably all know, is a famous tea, and a very good one at that.  So, I thought it fitting, in 2004, to buy a little dahongpao to keep for the occasion of graduation.

You can see a sea of crimson robes out there.  They’re puffy.  I thought it’s fitting.

Unfortunately, I’m not the one graduating, but fortunately, my wife is (or rather, was).  So, it gives me an excuse to break out the box I’ve been saving up.

This is a Best Tea House “1st generation transplanted” dahongpao, which is supposedly from a tree that is only one generation removed from the original three dahongpao plants.  Truthfulness in advertising aside, it’s a good tea.  So, I duly cut opened the seal of the bags (the tea was double bagged).  The bags were not vacuum packed.  Interestingly enough, upon opening the first bag, you can already smell the tea.

Looking like good dahongpao leaves.

I usually brew dahongpao with a heavy hand, but since we had a guest today, I tried it lighter so it wouldn’t be overpowering to the point of discomfort.  The tea is very sweet, and since I haven’t had this tea for years, I forgot that it is actually only medium fired, at most.  The roasting is actually quite well done, without being too heavy but just enough to kill the greenness that you sometimes find in newer yancha.  Also, there’s a hint of fruitiness in the tea that I don’t remember.  Perhaps it’s because I brewed it ligther, or perhaps because after five years of storage, the roasting has dissipated just enough.  There isn’t a whole lot of aged taste yet, confirming my theory that an oolong stored in a sealed environment won’t change much over only a few years — if you want real change, it either has to be stored in a jar with a minimal amount of air exchange, or be stored for a long time.  This is, basically, a slightly aged oolong.

The qi (I noticed I have not mentioned this word on this blog for months…. if not literally years) of this tea is quite decent.  Not a bad tea at all, and certainly didn’t disappoint after all these years.  I rolled up the bags, taped them up, and closed the box again.  Next time I open it, you can call me Dr. MarshalN.

The drain cleaners

June 2, 2009 · 3 Comments

I’ve been drinking a lot of drain cleaners these days, or in other words, puerh that are between 3-7 years old.  These are often the nastiest tasting things.  Whereas very young puerh (1 year or younger) are often quite pleasant to drink, and older things (7+) are usually fairly mellow, things that are in between can be disgusting.  They also begin to show their true colours.  Whereas younger puerh are often quite fragrant and light, once you’ve given the tea a few years, it can develop all sorts of flavours, from citrus to mint, and every conceivable taste in between.

The good thing about drinking something of this age is that you begin to have an idea whether it is any good or not.  If it’s already losing strength, as some do, then chances are it’s not going to get any better.  There are also ones that are intensely bitter without any sort of huigan, or just taste foul, strange, or, worst, hongcha-esque.

The linkage between a good tasting tea when young and a good aging tea when older is one of the biggest problem for those trying to evaluate and buy tea to press, and of course, the customer who eventually purchases them for storage.  Too often a good young cake turns out to be horrible after a few years, with no redeeming features and simply fades away.  In the puerh boom (and the post-boom world of today) there were many tea makers who popped out of nowhere to make tea.  Many of them used to be makers of other types of tea, be it green (guys from Shanghai area), oolong (a lot of Taiwanese tea guys), and hongcha (Fengqing factory, among others).  Then you have people who really didn’t know much about tea at all, or who never really made any tea, who jumped into the fray.  I have met a car dealer who became a puerh maker/merchant, and was selling some premium maocha pressed Lao Banzhang for a pretty price.  They will all tell you that they have had many years of experience in drinking tea (very often untrue, or including the time they had tea when they were three) as if it means anything.

Drinking, as we should all remember, has nothing to do with making.  A guy who can tell you if a shirt is well made or not probably has no idea how to start making one from scratch, unless he also happens to be a tailor by trade.  What makes tea any different?  A person who’s been growing tea for twenty years will, no doubt, have a pretty good sense of how it should be made.  A person who’s been drinking tea for twenty years will have some idea of how it ought to taste, and in the case of puerh, perhaps also how it ought to be stored.  Even to this date, very, very few people have actually taken a cake of puerh from its inception, through storage, to its mature state, and can attest to knowing how all these stages ought to be.  Many of the people whom I’ve met in Beijing and elsewhere who went and pressed their own cakes had, at best, mixed results.  Some of them had cakes that were obviously flawed.  Others had cakes that seemed all right, but after a few years of aging, turned out to be quite questionable.

It’s a pretty depressing thought, but I am increasingly of the belief that only those who live and work in Yunnan full time, year round, or those who have had a long working relationship with some of the farmers or factory owners there, will have access to good tea.  When my friend L visited Yiwu and spent a few weeks there with some contacts he had from CNNP, he said that all of the old tree farmers in one village were binded to long term contracts with this one person from Guangdong.  Everything else that goes on the open market as tea from this one place were all either “imported” from somewhere else, or were simply from inferior, plantation teas masquerading as better things.  If you’re a visitor who they don’t know, the farmer will show you a few bags of different teas.  You will try them all.  You will find that one of them is better than the others, with a suitably higher price.  All is well until, of course, you realize that there’s a vastly superior tea out there that you never got to try because the farmers won’t sell it to you.  The price will be right for an old tree tea (otherwise you’d think it’s too good to be true) but the tea won’t be.

Which is why I’m subjecting myself to the drain cleaners and trying to pick a winner among these, instead of going with the lottery of brand new teas.

Health benefits

May 21, 2009 · 10 Comments

I’m ready to kill somebody if I see another tea website with a big section on “health benefits of tea” and why you should drink more tea.  I saw a blog post today (to which I will not link — sorry, I really have no desire to link to such rubbish) that has the title “Infusing tea could cream HIV”, makes suggestive comments about how drinking more tea is good for you, and then linked to this article.  If you read the whole thing… in fact, if you read the first two paragraphs, you’ll see that this is all about how EGCG, the polyphenol that we’ve all heard about, can aid in blocking HIV infections through vaginal intercourse from the semen to the woman’s cell.  Adding EGCG to a vaginal GEL or something similar may help slow HIV infections.  That is, of course, great news, if it works.

Except that it has NOTHING whatsoever to do with DRINKING tea.  Sorry for all the cap letters, but I’m annoyed.  Pretty soon we’re going to be hearing that drinking tea raises the dead, cures cancer, solves global warming, and lead to everlasting world peace.  The fact is that this study, from the excerpt provided in that little WebMD article anyway, has nothing to do with EGCG in your body and everything to do with EGCG acting as a chemical that helps destroy a compound that makes HIV more effective in infecting cells.  So please, stop trying to sell tea because it provides health benefits.  We drink it because it tastes great, because it’s interesting, because it’s a good conveyer of caffeine.  Sure, some people drink it for health benefits, and that’s fine.  But surely, you must be able to sell tea, good tea anyway, without having to resort to “this is good for you” and “drink this and it will make you live longer”?  Or maybe, the tea you’re selling is so terrible (or terribly overpriced), that’s the only way to sell it.  If that’s the case, I’m sorry.

Aged oolong of unknown vintage

May 21, 2009 · 2 Comments

One of the problems with drinking aged oolong is that you never know how old the thing is.  Whereas with puerh the progression is fairly predictable, and taste can be a reflection of time passed at least down to blocks of five years, aged oolong does not afford the drinker such luxury, and can be wildly varied in taste and feel.  The culprit here is really the roasting, which changes all sorts of characteristics for the tea and can greatly affect how one perceives it.

I have been talking to some Taiwanese tea farmer who entered some aged oolong in a competition this year that were eventually rejected.  I just tried the tea yesterday, and it was somewhat light, sweet, aged, certainly, but not that aged.  The problem, he said, was that it wasn’t roasted enough, so the leaves still seem green and the judges felt it wasn’t really an “aged” taste, even though it has some years behind it (not that you would know if you didn’t know what you were looking for).  I tried another tea he sent me today,

And it’s very different.  The tea is more roasted, less fragrant, but also sweeter in a way.  The thing is, much of this is really just due to roasting, I think, and not a lot to do with the tea itself.  Instead of coming out yellow, the tea comes out a little more brown

For the uninitiated, a roasted oolong and an aged oolong might not seem all that different.  In fact, very heaviliy roasted oolong tend to taste quite similar to certain types of aged oolong.  I tend to like the lighter types — where roasting is not heavy and reroasting was not done (or done very sparingly).  I do wonder about the possibility of eventually holding on to some of these things for long term storage, but the risk of failure in this case is high.  Unlike puerh, oolongs can go bad in the form of sourness or simply dissipation of taste.  Until I find a good way to solve this problem (which entails, of course, experimenting with storage) I will just have to keep getting it from the farmers.

Pumidors

May 14, 2009 · 6 Comments

As I think I’ve mentioned a few times before, I am writing a column for a tea magazine in China, especially on issues of cross-cultural tea habits.  I was thinking about writing on the topic of pumidors (puerh humidors) — a rather unique American thing, I think, especially when you are talking about elaborate setups.  I am interested in what people have done, and would appreciate if anybody can volunteer a picture or two of their creation.  Please leave a comment if you have something to share.  Thanks

Zhizheng “Hongyue”

May 12, 2009 · 4 Comments

Through the randomness of the web I found this teashop called Zhizheng Tea. They seem to specialize in high end puerh, and claim to be a Sino-British venture of some sort.  There are some cakes listed, but with awfully little description — many of them are simply described as “pressed with high end maocha” or some variation thereof.  The pictures of the cakes look nice, although with a touch of sharpness that only really comes with too much photoshop or editing, and are not likely to reflect how they actually look in person.  I was curious what this shop is all about, and seeing that the cakes are priced far out of my reach, I opted for the relatively cheap samples.

The first thing about the samples is that they are indeed very cheap when compared with how much the cakes cost.  In fact, per gram, the samples are almost half the price of the cakes.  Of course, buying lots of samples in order to get 400g of tea is a rather perverse way of buying puerh, and may very well affect the aging process, but I suppose if one’s goal were simply to buy tea to drink now, that’s not entirely a bad way.

The samples come in these bamboo cases (you see one on their home page).  I just happened to have ordered three samples, which means I got one of these three pack pouch as pictured.  They look nice.  They’re not terribly practical, however, as tea bits do end up in the crevices of the bamboo weaving and when you try to open it after they’ve taken a long flight… you can imagine what happens.  I had a lot of tea bits on the table.

Packaging is not that important, at the end of the day.  The tea is.  I tried each of the samples once already, but I thought I should only write something about it on the second try.

Today’s tea is the Hong Yue, red moon.  There is no information about where this tea is from other than that it is maocha from 2005 that’s pressed this year.  I am guessing somewhere in Menghai county, possibly from one of those rather strong-tasting mountains.  If I have to make a guess I would say Bulang area, without making any claims about its precise location.

Now, the dry leaves don’t look all that remarkable, but then, they rarely do.  Looks, after all, are rather deceiving.

Taste, however, is not, and this tea, I can safely say, is strong.  There’s a bitter edge to the tea, only very slightly tempered by time and age.  It has lost the greenness of the young puerh, and is moving into that 5-7 years old taste profile.  The tea has body, strength, and character, and is the kind of stuff that I like to find in a younger puerh.  It also has energy, which is very nice.  The bitterness can easily turn off some of the less hardcore of puerh drinkers.  This time I made the tea a little weaker.  The taste is still strong, although not quite as punchy, but that may be a good thing.

I find it interesting how they suggest using a relatively large gaiwan, rather than a Yixing pot.  While I used to subscribe to the idea that using a gaiwan gives of more of the “true” taste of the tea, without the compounding effect of the Yixing pot, I no longer think that’s relevant.  After all, if I drink all my young puerh with the same pot anyway, then the problem of teaware affecting the tea is no longer an issue.  If a certain tea doesn’t work with my wares, well, too bad, I will just drink something else.  Besides, I think great tea will be great no matter what ware you use.

Needless to say, this isn’t much of an issue here.

The leaves are somewhat broken here, but that’s partly because of the sample effect.  They are nice and sturdy, without being tough, and has that feeling of stickiness on them.  Overall, I find this tea to be quite enjoyable.  Whether or not it is worth the price of admission is really dependent on the individual.  Personally, I find it hard to sink that amount into a cake of new tea that I don’t plan on drinking for a while, but as with all consumption, only the willing buyer pays.

Chataku by the dozen

May 8, 2009 · 5 Comments

Well, not quite a dozen… but I’ve grown quite attached to these things, and have obviously collected some over time

They usually come in sets of five, although the one on the bottom right I only have four of.  I like the metal ones, I think they provide a nice contrast against the porcelain cups.  Another important thing though is that they’re heavier.  The wood ones I feel are too light and flimsy, as if the cup is going to tip over any time.  With a metal one I don’t feel that imminent danger.  They also serve a practical function — they help the cup dissipate the heat, which makes the tea hit drinkable temperature faster.  Otherwise, I will have to wait longer.  Of course, they also make tea cups easier to hold when hot (by me avoiding touching the cups all together) and save the surface of my wooden trays.

So all in all… a pretty addition to my set, and one I never go without these days.

Using a gaiwan

May 5, 2009 · 7 Comments

Well, here it is — a silly little video on how to use a gaiwan and a few ideas on what works and what doesn’t.  It’s pretty basic.  For most of you, it’s probably useless.  I just thought that given all the stuff out there on Youtube — mostly with extremely elaborate procedures and all that, it really isn’t that instructive for those who aren’t into the performative side of things.

Let’s see if this works….
